- LUBRICATOR.

. Application filed August'l, 1922. Serial No. 585,397. if v/ i The invention relatesrrto lubricators and refers more particularly to locomotive` lubricators. The invention has for .its object the provision oi a unit construction of locomotive lubricator having a pluralityof lubricant vcompartments which respectively communicate with cylinders(A using steam at di-lerent pressures. With this and other ob In compoundlocomotives, the high pres` sure cylinders use'a different lubricating oil from that used in the low pressure cylinders, and heretofore vseparatelubricators for the high and rlowu pressure cylinders have been employed. `With my construction, different lubricating oils areffed; tothe high and low pressure cylinders from a single lubricator.`

As shown intheldrawings, 1 yisfthe condensing chamber of the `lubricator inthe upper. portion of the body,` and 2 l and 3 areseparate lubricant chambers which containv the different lubricating oils, in the lower portion of the-body,lthese lubricant chambers being separated bythe transverse partition 1 formed integral with the body.

5 and 6 are feed valves adjustably mounted at the lowerends of the lubricant chambers 2 and 3 respectively for controlling the passage of the lubricating oils from these lubricant chambers through vthe outlet pipes 7 to the high pressure and low pressure cylinders respectively. Each feed valve is adapted to variably restrict the axial passageway 8 in the nozzle 9,y this passagewaycoinmunieating with an outlet pipe 7 through the verticalpassageway 10 and thelateral passageway 11. 'l y The lubricating` oil is forced from each lubricant chamber by the hydrostatic head of water in thecondensing chamber. Both the condensing chamber andthe lubricant chambers` are subjectedto full boiler pres- I sure and by means of the equalizingpassages the-points where the lubricating oil leaves full boiler pressure.

ot lower specific gravity than the water also helps to fioat 1t up through the feed valve the luliiricatorare also subjecttofull boiler pressure so that the hydrostatic head of water in the condensing chamber above the lubricant chambers is lthe force which drives the lubricating oil out of the reservoirs past the feed valves and through the nozzles and upwards to the delivery points. The lubri-- eating oil is then picked up by the stream of steam, and water which is :passing through each outlet pipe due to the fact that the pressure at the steam chest where the oil is introduced for lubrication is always less than the The `fact that the oil is nozzle and vertical passageway, but the principal force is due to the hydrostatic head of water in the condensing chamber. The steam from the boileris admitted through the pipe 12 at the top` of the lubricat-or body and above the Vcondensing chamber 1 and -controlled by the valve 13. Some of this steam condenses in they condensing chamber 1Q and some isv led to the lateral passageways 11, connecting into the outlet pipes 7 by'means of the outer and inner equalizing passageways 14 and 15 respectively leading from the upper end of v.the lubricator `body above the` condensing' chamber, there being a separate equahzing passageway foreach lubricating oil outlet pipe. The inner lequalizing passageways are,

formed in the wall `of the condensing chamber, while the outer equalizing passageways are formed by bent pipes.

` Some of the water formed condensed in the condensing chamber 1 is adapted to flow` i-nto the lubricant chamber 2 through the upper verticalpassageway 16 opening into the lower end ofthe condensing chamber, the lateral passageway 17 opening into `the lower end of lthe upper vertical 'passageway 16 and the lower vertical passageway 18 `opening into the llower portion of the lubricantr chamber at 19 and adapted to communicate with the lateral `passageway 17. This'lateral passageway liscontrolled by the valve 20 adjustably mounted in the front side of the lubricator body. Some ofthe water formed by the steam condensed in the condensing chamber 1 is adapted to iiow intoj the lubricant chamber 3 through the upper `vertical passageway 16, the lateral passageway 17, the second lateral i passageway 21 adaptedto communicate with the lateral passageway 17 "and passing by the steam so y through the transverse wall `4 and the lower vertical passageway 22 which opens into the lubricant chamber near its lower end through the port23. n

The, lubricant chamber .2 communicates with the axial passageways 8 in the nozzles 9 through the vertical passageway 24 formed in a boss upon the transverse wall 4 and the lateral passageway 25 extending longitudibelow the nozzles, which latter in turn areV 'adapted to communicate with the nozzle passageways.

The lubricant chambers 2 and 3 may be illed withv the lubricating oils through the filler plugs 30 and 31 respectively.

In operation, steam entering the pipe 12 from the boiler passes into the condensing chamber 1 and also the outer and inner equalizing passageways v`14 and 15 respectively for each lubricant compartment. steam entering the condensing chamber' condenses and the water formed thereby passes downwardly through 4the upper vertical passageway 16, the lateral passageway 17 and then to the lower vertical passage- .way 18 intothe lower portion of' the lubricant compartment 2 as well `as the lateral ypassageway 21 and lower vertical passageway 22 into the lower portion of the lubricantA compartment 3.y This water displaces the lubricating oils in these compartments which pass downwardlyv through the vertical passageways upon the transverse wall 4 and to the aXial passageways in nozzles through the lateral passageways extending longitudinally at the bottoms of the compartments. The lubricating oils upon leaving the nozzles' lioat upwardly throughA the 'i water in the vertical oil passageways 10 and then horizontally through-the passageways 11 land out through the outlet pipes 7. The steam and water passing through the equalizing passageways to the outlet pipes produce an ejector action in` the passageways 11., picking up the lubricating oils and carrying the samev through the outlet pipes. v

From .the `above description, it. .will be readily seenthat I have provided `a single locomotive lubricator having separate lubricant compartments which are adapted to'be operativelyl connected to different steam lpressure cylinders.
